Patented Mar. 10, 1931 .UNITED STATES PATENT ol-FICE JULIUS L MOJONNIEBAND HARLEY R. PHILLIPS, OF OAK PARK, ILLINOIS, ASSIGNOB'S TO MOJONNIERBROS. CO., A. CORPORATION OF ILLINOIS FILLING-MACHINE Application filedOctober 18, 1926. Serial No. 142,225.

The present invention relates to filling machines for use in llingcontainers with commodities of a plastic nature, such as ice cream,sherbet, water ice, pomade, paste and the like. The machine hereindisclosed as an embodiment of the invention was developed by us moreparticularly for the purpose of lilling large metal containers with icecream and like dairy products. The machine herein disclosed has beenconstructed and operated. It is designed to fill metal cans of fromthree to ten gallons capacity and it does so at a rapid rate.

The invention particularly claimed in this which theL containers arebrought into correct position below the valve of the machine at the timeof delivery of the commodity. To

this end the conveyor is arranged so as to cor' rectly space thecontainers in respect to their positions longitudinally of the conveyor.This spacing takes place automatically as the containers are carriedalong by the conveyor. In conjunction with the mechanism for alsoarrange means for positioning or centering the containers laterally ofthe conveyor so that they will be properly presented at the deliverypoint. A tripping linger, whlch is operated by the container to bring'about a functioning of the machine, is utilized in a novel way inconnection with the' 'centering ofthe containers. 1

In carrying out our invention we employ a novel arrangement of thevarious .parts of the machine upon and within a box like main frame orcasing. The parts are mounted so as to provide the greatestaccessibility for nspection, replacement and repair, while at the sametime maintaining a high degree of eiliciency for the machine inoperation.

The' features of vour invention with thelr advantages will be more fullyunderstoodupon reference to the following detailed description taken inconnection wlth the ac companying drawings, while the scope of theinvention will be particularly pointedoutin the appended claims.

The machine hereindis'closed is along the lines of that shown in UnitedStates Patent case is the novel step by step mechanism by accomplishingthis longitudinal spacing, we

being located at the lower'end of the spout through which the commodityis delivered to the container; and Fig. 10 is a transverse sectionthrough the spout and cut off valve, the section being indicated -by theline 10-10 of Fig. 9. Throughout these views like char acters refer tolike parts. Ingeneral,` the machine illustrated comprises a vcommoditysupply connection A. through which the commodity is fed, a valve B bywhich the flow of the commodity is controlled, a cylinder Cl formeasuring the commodity charges, a spout D through which the commodityflows on its way to the container, a conveyor E by which the containersF are brought to filling position below the spout D,

and an auxiliary valve G at the mouth of the spout D.

'Upon examination of the drawings in detail, it will be seen that thecylinder fC is positioned upon a main frame 20 having a plurality ofsupporting legs 21.` The frame isa box like structure which forms acasing for many of the movable parts of the machine. In order that readyaccess may be had readily worked upon. Obviously, the covers 25, 26, and27, may be attached to the main frame or casing --20 in various wayswhich need not be particularly described.

The supply connection A is, in the present instance, merely a connectingtube or pipe 28 through which the commodity is supplied. Commonly, inpractice, the pipe 28 forms the outlet of a hopper located above themachine. In some installations the machine is on one ioor of thebuilding, and the hopper from which the pipe 28 leads is on the floorabove. Since there is but one cylinder C, the hopper will not be dividedinto compartments as in the aforesaid Patent No. 1,502,314, but willconstitute a single container from which the supply passes to thefilling machine.

The pipe 28 is suitably connected at its lower end to the valve casing29, in which the main valve B of the machineis located. As clearlyshown, the casing 29 is provided at its upper end with a flange 68.r-l.`his flange is mated with a flange 69 upon a collar 70 whichsurrounds and is secured to the lower end of the pipe 28. The flanges 68and 69 are secured together by bolts or other suitable means. rlhe valveB is mounted for rotation on a horizontal axis` after the manner of thevalve shown -in the patent to Geyer No. 1,401,150, dated December 27,1921. The valve structure is also shown in the application of Julius J.Mojonnier, Serial No. 75,953, filed December 17, 1925. f' rThe rotarymem- ;ber 30 of the valve B fits into a transverse bore in the valvecasing 29, and is provided with a suitable passage 8,4a which cooperateswith passages, 84h, 84 and 82a in the casing 29 to guide the commodityfrom the pipe 28 to the cylinder C in one position of the valve, andfrom the cylinder C to the discharge spout D in the alternate positionof the valve. The rotary element 30 is provided with a single passage84aiwhich is shaped as shown more particularly in Fig. 5a. ln theposition Shown in that figure, passage 84a establishes connectionbetween passages 84h and 84`of the casing 29, that is to say, fromsupply conineaeia I necti'on A tohcylinder C. In the alternate positionof the member 30, passage 84a connects passage 84"l with outlet 82a andthus 'connects cylinder C with outlet spout D. The

rotary member 30 is held in place in casing 29 by a removable head 45and thumb screw 46. The disk or head 45 is of slightly greater diameterthan the bore in which member 30 fits and thus provides a bearingshoulder at the end of the valve. The opposite end of the member 30 isprovided with a similar shoulder 81". The two shoulders bear againstopposite ends of the casing and allow the member 30 to be rotated thenecessary distances. With this construction it is only necessary tounscrew the thumb screw 46 and then the entire valve member 30 may bereadily removed from the casing 29 for cleaning the parts. The rotaryvalve member 30 .is provided witha crank arm 31 which is connected atits end distant from the thumb screw 46 with a connecting rod 32 whichis reciprocated through the agency of a cam roller 33 and a cam track 34upon a cam member 35 keyed to the upper end of a vertical driving shaft36 journaledin parts of the frame 20 near the rear end of the machine.The cam wheel 33 is carried by a pivoted lever 37 which is connected atits free end to the rear end of a rod 38, which in turn is connected atits forward end to the rear end of connecting rod 32.` rlhe rod 38 isguided in its recprocations by a guide member 39 secured to the top ofthe casing 20 of the machine. A short ink 40 serves as the connectingmeans between the lever 37 and rod 38. The pivotal connection of thelever 37 is provided by a pivot pin 41 which extends through an openingin a boss formed at the end of the lever 37 and finds bearing in anopening through a thickened portion 42 of the main frame 20. A trans.-verse pin 43 and associated washer 44 hold the pin 41 in place. lt willbe seen from the relation of these parts that each rotation of thevertical driving shaft 36 causes the valve 30 to pass through a completecycle which includes two positions. In one of these the commodity isguided into the cylinder, and in the other it is directed as it passesout of the same. rlhis vparticular valve structure has been employed byapplicants assignee for some'time and of'itself constitutes no part ofour present invention.

rlhe cylinder C is mounted upon the upper side of the casing 20 andexten-ds somewhat beyond its forward edge, as clearly illustrated inFig. 1. The forward end of the cylinder is fitted to therear end of thevalve casing 29. The cylinder is provided with a piston 60a of anypreferred construction which cooperates with the cylinder to supplymeasured charges of thel commodity to the container after theA u mannerdisclosed in the aforesaid Patent No. 1,502,314. The piston isreciprocated by power transmitted from the upright driving shaft 36 atthe rear of the machine. Thecam member 35 which, because of this con`struction, also serves as a crank disk. The

mounting of the pivot 48 upon this disk produces in eect a vcrank uponthe upper end of the vertical shaft 36. The crank pin 48 is connected tothe rear end of a connecting rod 52 which is connected at its forwardend by means of a yoke 53 with trunnions 54 formed on the upper andlower sides of a block 55 which is fixed to an intermediate rock arm 56.As clearly shown, the member 55 is secured to the arm 56 by machinebolts 57 and the upper and lower portions of the member 55 extend aboveand below the arm 56 in such a way as to bring the -trunnions 54 in linewith thefcenter of the arm. By this construction the connecting rod hasa lixed pivotal connection with the arm 56 which constitutes anoscillating, member intermediate of the shaft 36 and the cylinder C. Theconnection between the shaft 36 and the piston of the cylinder iscompleted through a second connecting rod 58 which is connected at itsforward end to the piston a, and at its rear end by means of a yoke, 59to a pivot pin 60 carried upon a reciprocating block 61 mounted foradjustable movement in a slot 62 formed in the rock arm 56. Thisadjustment is accomplished through an adjusting screw 63 which hasthreaded engagement with an opening through the block 6l and only rotaryengagement with bearings 64 on the upper l side of the rock arm 56 nearits pivot 65. A

hand wheel 66 on the -end of the screw63 enables the latter to berotated for shifting the block 61 and thereby the pivotal connectionbetween'the connectlng rod 58 and the oscillatmg member 56. Because ofthe nearness G of the Wheel 66 to the pivot 65, it has only slightmovement as the member l56 is oscillated and'may be readily turned byhand even while the machine is in operation. .The adjusting screw 49 :atthe rear end of rod 52 constitutes a primary means for adjusting thethrow ofthe piston of the cylinder. vThelatter may be given a furtherrefined adjustment by means of the hand wheel 66, as just explained. Itmay be pointed out that the yoke 53 upon the forward end of theconnecting rod 52 is split for the purpose of as-VA sembling the yokeupon the trunnions 54.

- The parts of the yoke 5 3 are held together upon the rod 52 by anysuitable means as thebolt and nut connection 67. It will be seenthateach rotation of the vertical driving shaft 36 will cause a complete toand fr0 movement of the cylinder piston. In normal operation therearward movement of the piston will draw in a charge of the commodityfrom the supply source, and the forward movement of the same will -orceit through the spout D into the container. This to and fro movement ofthe piston will synchronize with the movements of the oscil lating valveB.

Beneath the main valve B is located the spout D. This comprises atubular member 71 which is provided at its upper end with a head 72finished so as to lit accurately and snugly against the lower end 73 ofthe valve casing 29. The head 72 is provided with a lateral arm 74 whichterminates in a boss 75. The latter is positioned, directly below asimilarboss 76 upon an arm 77 extending forward from the valve casing29. The bosses 75 and 76 are provided with registering vertical openingsfor the passage of a pin 78 having a head at its lower end and threadedat its upper end for the reception of a knurled nut 79. It will be .seenthat by unscrewing the nut 79 the pin 78 may be withdrawn. In such casethis portion of the spout D will be free from the structure above it andthe same may be removed. On the far side of the head 72 from the arm 74is avprojecting flange 80. This flange is adapted to rest on a ledge 81extending outward from the casing 29, as clearly shown in Fig. 1. Whenassembling the spout, the flange 80 is first placed upon the ledge 8land the spout` forced upward until the bosses 75 and 76 come intocontact and alignment. Then the pin 78 is inserted and the nut 79applied. It will be seen that this structure is such that the spout Dmay be readily removed from the casing 29 and the under side of thevalve casing readily and thoroughly cleaned, while the spout may also becleaned after removal from the machine. It may be pointed out in thisvconnection that the auxiliary valve G is also provided with a removableconnection with its actuating parts so that the spout D and valve may beremoved together from the other parts of the machine'.

The valve G is located at the lower end of the spout D and vcomprisestwo knife members or blades 82, 83 which are mounted to oscillate in aplane at right angles to the axis of, the spout. In the present instancethis plane is a horizontal plane. The members 82 and'83, when inengagement, contact along a diameter .of the tubular member 71. Whenseparated., asl clearly shown by the dottedline positions of Fig. 9,they are entirely clear of theA o'pen end of the member 70. In thiswaythey do not interfere with the passage 'with a laterally extending arm91 which moves with the plate as a unit. It may be made integral withthe plate or as a separate member fixed to the plate. The outer end ofthe arm 91 is provided with a handhold 92 by which the arm 91 may bemanually moved. Obviously, such manual movement will rock the plate 82about its pivot pin 87. In this way it may be moved from open posi-`tion to closed position and vice versa. In order to transmit thismovement to the plate 83 an interconnecting member in the form of arotatable plate 93 is provided. This rotatable plate lies directlybeneath the fiange 86 upon the lower end of the spout member 71, and isadapted to rotate upon a bearing shoulder 94 upon the same memberdirectly beneath the flange 86. The pla-te 93 is thus confined betweenthe flange 86 on the upper side and the knife members 82 and 83 on theunder side,y as clearly illustrated in Fig. 10.v

Pin and slot connections are provided between plate 82 and plate 93.Similar connections are provided between plate 83 and plate 93. In theplate 93 there are two slots 95. Cooperating with these'slots are twopins 96. One of these pins is fixed in the member 82 and the other isfixed in the member 83. The slots 95 extend radially and the effect ofthe movement of plate 82 from the full line position of Fig. 9 to thedotted line position of that figure causes the associated pins 96 tomove outward in their slots 95. Thus plate 82 rotates plate 93 and plate93 in turn rotates plate 83. The movement of arm 91 in one directionwill close the cut ofll valve G by bringing plates 82 and 83 to-getherwhile the movement of the arm 91 in the opposite direction will opensaid valve by separating said plates.

For the purpose of actuating the arm 91 in timed relation with the valveB, a connection is provided with the connecting rod 32. This includes asleeve 101 which is rmly clamped to the rod by screws 102. The sleeve101 has a downwardly projecting arm 103. To the lower end of this arm ispivoted a link 104. The forward end of the link 104 carries a yoke 105.The bifurcated arms of the yoke 105 straddle the member 91 and areprovided with-openings through which extends a bolt 106 which is headedat one end and provided with a nut at the other so as to securely attachthe yoke 105 to the arm 91. The arm 91 is, obviously, apertured for thepassage of the bolt 106. As before pointed out, the removal of the bolt106 disconnects the eut otl' valve from the link 104 and so, enables thespout D and valve G to be removed as a unit from the rest of themachine. When so removed the same may be readily cleaned.

The containers must be fed to the delivery point beneath the spout D. Asbefore stated, the machine herein disclosed has been devised with a viewto handling containers of large capacity. The containers illustratedherein are metal cans capable-of holding as much as step movement whileat the same time properly positioning the containers as they traveltoward and finally stop in the position directly beneath the spout Dready to receive the contents of the cylinder C. The conveyor comprisesuprights 107 and 108 of Variable length. Each upright is provided withan adjustable foot 109. By means of these feet the conveyor can be linedup so as to give a rectilinear path for the upper stretch of theconveyor chain 110/even though the floor on which the conveyor ismounted vis uneven. Besides the uprights, the conveyor includeslongitudinal members 111 and 112.- These members are preferably angleirons secured to the tops of the uprights 107 and 108 respectively. Asclearly shown, the portion of the conveyor extending along the front ofthe' machine comprises a table or runway made up of channel irons 113arranged in an inverted position. Between the two sets of channel irons113 is a space for the passage of the conveyor chain 110. A channel-iron114 lies beneath the upper stretch of the chain 110 and serves tosupport it. At suitable intervals the channel irons 113 and 114 aresupported by transverse members 115. Obviously, these different Ipartsmay be variously arranged. At some points the uprights 107 and 108 areconnected by transverse members 116 and these carry channel irons 114for the support of the lower stretches of the chains. The chain 110passes over suitable conveyor wheels 117, one such wheel being locatedat each end of the conveyor. These wheels are preferably mounted each inaI frame 118 which is secured to uprights of the conveyor or othersupporting means. Thus in the case of the conveyor' E, we provide anauxiliary bracket97 which is secured at one end to the adjacent frame118, and at the other end to a portion of the main frame 20. One of theWheels 117, in the case of each conveyor, is preferably mounted in itsframe 118 for adjustment. Fig. 4 wherein the wheel 117 is journaled in 5movable bearings 119 arranged for adjustment by screws 120. Thelongitudinal members 111, 112 of the conveyor, as clearly illustrated inFig. 1, serve as guides and keep the containers F within bounds. Theconveyor E, which serves to feed the containers to the delivery positionbelow the spout D, has one of' its wheels 117 mounted in its frame 1,18upon a shaft 126, the axis of which is parallel to the axis of thecylinder C, but lies to one side of the vertical 'plane through thecylinder axis. The shaft 126 has keyed to it a ratchet wheel 127. Thisratchet wheel is located at the end of the shaft nearest the casing 20.A rock arm 128 A is mounted for free oscillation upon the shaft 126adjacent to the wheel 127. The rock arm 128 carries a driving pawl 129which falls by gravity into engaging position with the teeth of theratchet wheel 127 as the arm 128 is oscillated. The oscillation of thearm 128 is provided through connectionswith the vertical lshaft 36 atthe rear of the machine. These connections include links and crank arms.The first of these is a link 130 which is connected at one end to therock arm 128 on the shaft 126, and at the other end to the outer end ofa crank 131 which is pivotally mounted within the forward end of thecasing 20 beneath the cylinder C. The connection of the link 130 withthe rock arm 128 includes a terminal member 132 which is pivoted at thepoint 133 to the arms of a yoke 134 pivotally mounted on the pin 135 ofthe rock member 128. The terminal member 132 4o has a threaded bore intowhich the end of a threaded rod 136 of the link structure 130 passes..The other end of the rod 136 extends into a like threaded bore in aterminal member 138. The center of the rod is -provided with an angularhead so that the rod 136 and its terminal members 132 and 138 may bemoved toward or from each other, the threads on the opposite sides ofthe head being right and left hand threads. Lock nuts 137 serve'4 tohold the parts in adjusted position. The terminal member 138 isconnected by a pivot 150 to a bifurcated member 151, the bifurcated armsof which pass on opposite sides of a block 55139 which has trunnions 140upon its upper and under sides, which trunnions pass through o enings inthe bifurcated ends Such a mounting is illustrated inl of the mem er151. The blockV 139 travels in j a slot 141 formed in the outer end ofthe crank arm 131. By means of a screw 142 mounted for free rotation inthe crankV arm 132 and having threaded engagement with an openingthrough the block 138, it is possible to adjust the position of theblock 139 35 in the direction of the crank arm 131. v- By.

j means of the threaded coupling member 136 the length of the link 130may be accurately adjusted, and by means of the adjusting screw 142m thecrank arm 131 the stroke of the link 130 and, consequently, the strokeKa pivot pin 143. The latter is secured in a i stirrup 144 mounted withinthe casing 20 beneath the cylinder C. .This stirrup is secured at itsends to the casing 20 by any suitable means as nuts and bolts 1 45. Thecrank arm 131 is actuated by force applied at an intermediate point. Forthis purpose a link 146 is employed. This link is connected to the rockarm 131 by pivot pin 147. The opposite end of the link 146 is similarlyconnected by a pin 148`to the outer end of a crank arm 149 of a bellcrank lever 156. The latter is provided with a long central hub orsleeve which is mounted upon a vertical pivot pin 157 xed at its lowerend in the stirrup member 144 and at its upper end in a projection 158from said member. The upper crank arm 159 of the'bell crank lever 156 isconnected by a pin 160 with a bifurcated terminal member 161 threadedupon the forward end of a connecting rod 162, a lock nut 163 serving tohold the parts in adjusted position. The rear end of the rod 162 issimilarly threaded into an opening in the eccentric strap member 164, alock nut 163a serving in thisinstance to hold the parts in adjustedposition. The eccentric strap is d1- vided and its parts are connectedthrough the instrumentality of bolts 165 and nuts 165. The eccentricstrap 164 surrounds and closely embraces an eccentric 166 on the underside of a beveled gear wheel 167 mounted upon the vertical shaft 36 anddriven, as we shall see later, independently of that shaft.

As the wheel 167 is rotated, each revolution will produce a to and-fromovement of the connecting rod 162. Such movement -will oscillate thebell cra-nk lever 156 and the latter, by reason of the link 146, willrock crank arm 131 about its pivot pin 143 and cause a Ito and fromovement of the link 130, thelatter in turn producing a suitableoscillation of the driving pawl 129.

Each advance of the ratchet wheel 127 by its pawl 129 will cause theconveyor chain 110 to advance the distance of the two links. As clearlyshown, every other link in the chain is provided with a lug 168. Theselugs engage behind the containers and advance them each time the'ratchet wheel is moved Yone step. The distance between the lugs 168 isthe distance between the centers of adjacent containers when engagingthe lugs upon the conveyor chain 110. It will be noted that the uppersurfaceK of the links of the upper stretch of the conveyor is elevatedslightly above that of the adjacent floor provided by the invertedchannel arms 113. The floor thus provided tends to hold the containersback while the chain tends to advance them. The result is that thecontainers are gradually brought up against the lugs 168 as they advancealong the conveyor toward the filling position. These lugs upon theconveyor chain, in conjunction with the adjacent floor of the container,as well as the guides 111, 112, provide thus a means for adjusting thecontainers in direction lengthwise of the conveyor. Even though thecontainers are not accurately positioned upon the conveyor by theattendant whose duty it is to put them thereon, yet they will, aftertraveling a short distance along the conveyor, be brought up intoengagement with their respective lugs 168 and thus be accurately spacedfor the filling operations which are to take place. The containers arefurthermore adjusted laterally of the conveyor E. This is brought aboutby a long yielding finger 169 which lies opposite the trip finger 170 bywhich the mechanism for filling is set in operation when a containercomes into filling position. The spring finger 169 is pivoted at thepoint 171 to a bracket 17 2 upon one of the uprights 107 of' theconveyor E. Its forward end, as clearly shown in Fig. 3, extends into aposition directly opposlte that of the forward kend of the trip finger170. At an intermediate point the finger 169 is provided with a downwardprojection 173. The lower end of this projection is connected to one endof a spring 174. The other endl of the-spring is attached to a fixedpart of the frame of the conveyor. The function of the spring is tocause the free end of the finger 169 to yieldingly press toward thevcenter of the conveyor in opposition to the trip finger 170.

The forward end of the finger 169 rides4 upon the floor of the conveyorprovided by the inverted channel irons 113. It normally lies in positionto be engaged by the oncoming containers. It yields lto the pressureIapplied by the containers but in so'doing forces them against the tripfinger 170. The joint action of the fingers 169 and 170 centers thecontainers or otherwise properly positions them with reference to t-hewidth of the conveyor E.-

After the containers are filled they are still advanced step by stepalong the conveyor E. Of course, they may be manually removed directlyfrom this step by step conveyor after being filled. In other instances,it may be preferable to conduct them to a continuously travelingconveyor, such as the conveyor H. In the inst-ance illustrated, the

conveyors E and H meet at a right angle and the chains 110 upon theconveyor H are not provided with lugs as they are upon the conveyor E.Furthermore, two chains 110 are employed upon conveyor H, while only onesuch chain is employed upon conveyor y who scrapes off the surplus creamor other commodity from the tops of the containers and places it in theextra container on the table 176. As soon as the extra container isfilled, it is shoved on to conveyor H and carried away. Another emptycontainer is then taken from the table 175. The attendant, who uses aspatula or other tool for scraping the surplus commodity off of the topof the containers, places a sheet of paper on the filled container. Thescraping operation is merely to give the commodity in the container asmooth upper surface so that the paper may be readily and promptlyapplied to keep the contents free from contamination. The conveyor H issimilar in construction to t-he conveyor E, and need not be describedmore particularly. The main dierences have been pointed out. As clearlyshown, the table 175 is mounted upon the upper ends of uprights 107 and108, while the table 176 is secured to a plurality of uprights 107 andsupported by a brace 177. Since the construction of t-he conveyor H isthe same, except for the differences noted, as that of the conveyor E,like reference characters will indicate like parts in both.

It is, of course, important not to discharge a cylinderful of thecommodity through the spout D unless a container is in position toreceive the same. Accordingly, trip mechanism isprovided which will setthe discharging mechanism in operation only when a container ispositioned beneath the spout D. As previously noted, a trip finger 170normally lies in the path of travel of the containers and when acontainer stops beneath the discharge spout D this trip finger isactuated to cause the vertical driving shaft 36 to make. one revolution.During this revolution the cylinder piston is given one complete to andfro movement and the valves B and G are fully operated. The rotation ofthe vert-ical shaft 36 is dependent upon a pin clutch associated withthe beveled gear wheel 167. This clutch includes a disk 178 keyedadjacent to the lower end vof the shaft 36 and a cooperating pin 179which is capable of Vertical movement in an opening in the hub of thebeveled gear wheel 167. When unhindered, the pin 179 will enter anopening in the disk 178 and the shaft 136 will rotate in response to therotation of the wheel 167. The upper end of the pin 179 carries alaterally extending pin 180 upon which is mounted a cam wheel 181.

Normally, the cam wheel 181 rides up over the cam surface 182 upon theend of a pivoted arm or member 183. As the wheel 181 rides up over thecam surface 182, it withdraws the pin 179 from the disk 178 and theWheel 167 rotates one revolution without rotating the shaft 36. Whenthat revolution is completed, if the cam 182 is still in position toengage the cam wheel 181, the pin 179 is held up and can not drop intothe opening in the disk 1,78. Consequently, the wheel 167 makes anotherrevolution Without rotating the shaft 36. Thus it will be seen that aslong as thecam face 182 is in position to he engaged by the cam wheel181, the shaft 36 will not rotate. Since the shaft 36 must rotate inordei` to discharge the commodity into the container, it becomesnecessary to shift the cam surface 182 out of the path of the cam wheel,181 whenever the right condition exists for the discharge -of thecommodity. F or this purpose the arm 183 which carries the cam face 182is mounted on a vertical pivot pin 184 suitably secured to a casing 20.Normally, a spring 185 acts between an arm 186 upon the cam member 183and a fixed point on the frame to hold the cam face ,182 in position tobe engaged by the cam wheel 181. To rock the member'183' against thetension of the spring 185 and in response to movements of the tripfinger 170, suitable link and lever' connections are employed. Theseinclude a link 187 which connects the arm 186 of the cam member 183 witha lever 188 which is pivoted to a bracket 189 carried by a transversemember 190 of the frame structure of the machine. The lever 188 is inturn connected at a point some distance from its pivot to the rear endof a rod 191. The forward end of the latter is connected to an arm 192secured to the upper end of a vertical rod 193. The latter is mounted inhangers 194 secured to the. frontof the main casing 20. The trip finger170 `is secured to the lower end of the rod 193. ,With this constructionit will'be seen that a movement of the trip linger 170 to the right, asthe\parts are viewed in Fig. 5, will cause the rod 191 to move towardthe front of the machine with a consequent similar movement of the rod187 and the arm 186 upon the cam member 183. This forward movementwillthrow the cam face 182 out of the pa'th of travel of the cam Wheel 181.The result of this action will be, as before noted, to allow the pin 179to engage its opening in the disk 178 and thus clutch the shaft 36 tothe driving wheel 167 for at least one revolution. In order to providefor manually actuating the trip mechanism, the arm 192 is provided witha handheld 195. Byfa forward pull upon the latter the trip mechanismwill be actuated as just described. Furthermore, if it is desired tomanually operate the trip mechanism while examining some portion of themachine and standing near the center of the casing 20, the hand levers196 may be used. These are fixed at the opposite ends of a rod 197,which is journaled at its ends in the opposite side walls of the casing20. At an intermediate point the rod 197 is provided with a crank arm198 which is fixed upon the rod and pivotally connected at its outer endto the forward end of a rod 199. The rlatter is connected at its rearend to the inner end of the lever 188. The relation of the connectionsis such that a forward and downward pull upon either of the hand levers196 will bring about the trip movement previously described.

For driving the machine parts we preferably employ an electric motor 206suitably mounted within the casing 20 at a point near the rear of themachine and underneath the lower bearing of the shaft 36 which, by theway, is a thrust bearing employing a ball 207. This bearing is locatedin a'transverse member 208 of the machine frame. This member provides,with the frame members 209 and 210, suitable bearings for horizontalshafts 211 and 212, the latter being located directly above the former.The pinion 213 on the shaft of the motor 206 meshes with a gear Wheel214 keyed to the shaft 211. A pinion 215 is likewise keyed to the shaft211. The latter pinion meshes with a gear wheel 216 y keyed to the shaft212. The latter shaft carries a beveled pinion 217 which meshes with theteeth of the beveled gear wheel 167. By following out this train ofgearing, it will be seen that the wheel 167 is driven continuously solong as the motor 206 is in operation. In view of this fact, the step bystep mech-` anism which is driven through the eccentric 166 is alsodriven continuously, that is to say, as long as they motor is inoperation. The other parts of the mechanism, namely, the vcylinderpiston, the main oscillating valve B, and the cut off valve G, aredependent for their operations upon thel rotation of the shaft 36, andthe latter, as we have seen, is dependent upon the position of the tripmechanism for operating the pin clutch members 178 and 179.

In carrying out our invention, obviously many alterationsandmodifications may be made in the particular structures illustratedwithout departing from the spirit and scope of the invention. Likewisedierent parts of the disclosure may be used independently of each otherand still come within the purview of the invention. We, therefore,.donot wish to be limited to the exact constructions shown but aim to coverall those alterations and modifications which rightly come Within thescope of the invention, by the terms of the appended claims.
